Used as a plasticizer in polymers to improve flexibility and workability, especially in coatings, adhesives, and sealants. Provides good low-temperature performance and resistance to water extraction. Commonly found in cellulose-based plastics and synthetic rubber formulations. Also serves as a lubricant base stock and carrier fluid in cosmetic and personal care products due to its low volatility and mild skin compatibility. Occasionally used in fragrances as a solvent or fixative.
